This should only be enabled on filesystems, where the - file data is never changed externally (not through the mounted FUSE - filesystem). Thus it is not suitable for network filesystems and - other "intermediate" filesystems. - - NOTE: if this option is not specified (and neither 'direct_io') data - is still cached after the open(), so a read() system call will not - always initiate a read operation. - -'direct_io' - - This option disables the use of page cache (file content cache) in - the kernel for this filesystem. This has several affects: - - - Each read() or write() system call will initiate one or more - read or write operations, data will not be cached in the - kernel. - - - The return value of the read() and write() system calls will - correspond to the return values of the read and write - operations. This is useful for example if the file size is not - known in advance (before reading it). - 'max_read=N' With this option the maximum size of read operations can be set. |
